Macbook or Macbook Pro for Applied Mathematician

I will be joining Duke University (Durham, NC) as an applied math major with a research interest in applied neuroscience and Artificial Intelligence. So, should I buy a Macbook or a Macbook Pro for all the mathematical work that I will be doing? The work should include a lot of algorithm testing, simulations, mathematical modeling and large counting on numbers. Please advise on whether I should go for a Macbook or a Macbook Pro or perhaps a different laptop.

If you have to do a lot of number crunching it does not matter so much which make of computer you buy. What matters is the clock speed of the machine and how much processors it has. (The more the better)
